Local Exhaust Ventilation Surveys (LEV)
Hydro-X Air has designed a fully comprehensive inspection report inline to meet COSHH regulations for Local Exhaust Ventilation (LEV) Surveys.
This states that all LEV systems must be regularly tested, at least once within 14 months. As an LEV Testing company – our consultants are P601 trained, and when on-site part of their testing survey would be to inspect on-site logbooks, all paperwork relating to daily, weekly and monthly inspection works.
Local Exhaust Ventilation (LEV) Survey Services
A full photographic written report will be provided on completion of our testing work which would include as a minimum:
- System details
- System performance
- Site maintenance checks
- Inspection report
Are LEV Surveys a legal requirement?
Yes – if you are an employer, you must legally test your LEV extraction systems. Failure to do so could result in prosecution and a number of issues regarding insurance.
The systems have to be classed as being maintained in an ‘efficient state in efficient working order’ and all data associated with testing needs to be recorded. If an audit happens or if an insurance company looks into the business, records from the last 5 years need to be provided. A good repair company should be contacted if the system has any temporary/permanent operational damage or there is a great possibility of exposures to airborne contaminants.
HSG258 – Controlling Airborne contaminants at work (Local Exhaust Ventilation)
Local Exhaust Ventilation/LEV Surveys and LEV Testing services are extremely beneficial to an employer – and they can literally save lives. The HSG258 details how the competent person (the one tasked with conducting the lev tests) can help to prevent breathing problems for employees (via exposure to toxic elements).
HSG258 – Control of Substances hazardous to health (COSHH)
If a substance is used and there is a risk to someones health and safety (be that the employee, employer or a member of the public), the HSG258‘s guidelines must be followe.
They were applied in 1988 and sanctions could be handed out for misdemeanors a year later. The legislation concerning the control of substances has maintained the LEV in the workplace element consistently for over 30 years. Contrastingly, after multiple changes, the other elements have been improved to become more succinct.
What is an Local Exhaust Ventilation (LEV) System?
A local exhaust ventilation system is a structure with the primary objective of preventing unwanted exposures to a number of different elements in the air. These include Vapour, Fumes, Mist, Dust and Gases.
They are primarily in workplaces, although they have been known to feature in domestic properties too (if the landlord is particularly health and safety conscious). The better an LEV system is, the more effective it will be at removing airborne contaminants from buildings.
Most systems (that need an LEV survey) include a Hood, Air Mover, Air Arrestor, Ducting and a Discharge facility (like a fume cupboard). The Hood is the entry point for the contaminant with the ducting acting as an air conductor.
It is essential for the LEV Testing company to identify the different components:
- Machine guards need to be classified as they also extract contaminated air
- Furnaces/ovens that contain flues
- If large volumes of contaminated air are absorbed by the system, this needs replacing efficiently and a system needs to be put into place
